A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

The molecule is a radioactive tracer that latches onto immune cells when they're activated -- the status that immune cells, in particular T cells, assume when they're poised to kill tumor cells. "It's ...

What is positron emission tomography? Positron emission tomography (PET) is a non-invasive nuclear imaging technique which uses radioactive tracers. PET scans specifically look at the metabolism of a ...

Positron emission tomography (PET) is a type of imaging scan that doctors might use when diagnosing and treating non-Hodgkin’s lymphoma (NHL). It can be useful for identifying and staging the cancer.

New research has been published ahead-of-print by The Journal of Nuclear Medicine (JNM). JNM is published by the Society of Nuclear Medicine and Molecular Imaging, an international scientific and ...

Positron emission tomography (PET) scans can detect cancer earlier than other imaging tests. But some types of cancer are harder to detect on a PET scan. In particular, they may miss cancers that ...

Researchers in Japan are developing a medical camera that can simultaneously detect radioactive tracers used for PET and SPECT scans. The team has now demonstrated that the camera can image both ...

A patient checks into the hospital with difficulty breathing. Is inflammation to blame? How can physicians visualize areas of inflammation in the respiratory system in order to choose the best course ...

Researchers have found a surprisingly versatile workaround to create chemical compounds that could prove useful for medical imaging and drug development. Researchers have found a surprisingly ...

Researchers discovered a method for creating radioactive tracers to better track pharmaceuticals in the body as well as image diseases, such as cancer, and other medical conditions. In an advance for ...

Positron emission tomography, or PET scanning, a technique for tracing metabolic processes in the body, has been widely applied in clinical diagnosis and research spanning physiology, biochemistry and ...
